When ready to cook, set the temperature to 325F and preheat, lid closed for 15 minutes.
Combine the lemon zest, lemon juice, softened unsalted butter, dill, parsley, sea salt, and ground black pepper.
Generously slather the top of the salmon fillet with the mixture and top with a slice of lemon. You may allow marinating for about 10 minutes or so to absorb the mixture.
Place the salmon fillets on the hot grill grate, skin-side facing down.
Cook for 20 to 25 minutes, until it reaches an internal temperature of 145F and flakes easily, or until the salmon is cooked to your preferred taste.
Serve with Lemon slices and perhaps garlic-butter dip
How long do you cook salmon in the oven?
It will depend on the size and the thickness of your salmon, of course. If your filet is thick I'd say about 25 minutes in the oven at 400ºF. But it has a normal size I would say about 15 minutes or until salmon flakes easily with a fork.
